摘要：

In this Letter we discuss the use of Granger causality to the analyze systems Of Coupled circular variables, by modifying a recently proposed method for multivariate analysis of causality. We show the application of the proposed approach on several Kuramoto systems, in particular one living on networks built by preferential attachment and a model for the transition from deeply to lightly anaesthetized states. Granger causalities describe the flow of information among variables. (C) 2009 Elsevier B.V. All rights reserved.
